Re: 2001 Jeep Grand Cherokee 4.0
Eventhough in winters you would like to have warm air, the AC compressor will normally be switched on automatically with air on the windshield, to remove mist from the windshield. Also when driving with damp clotches, the windows will get misty without AC, just a thought.
When you remove the AC compressor, the belt routing will change and there will be less belt on the waterpump pulley, donīt know if that could cause any slipping.
There is a delete pulley, which comes in the place of the AC compressor pulley.Not sure where they sell it, but then you keep the same belt routing and the same belt.
Also most probably the compressor clutch bearing has seized and not the compressor itself. You could just get a new bearing and install it on the jeep without removing the compressor.
